ASX advises that Mr Robert Priestley has resigned from the ASX Board, with effect from today.

Mr Priestley said, "I am very conscious of the unique role that the ASX plays at the heart of Australia's financial marketplace, and with all of its participants. There has been considerable interest in the ACCC banking matter which may become a potential distraction for the ASX and my Board colleagues. "It is likely that this matter will take some time to resolve, and as there are limits to the information that can be discussed at this time, I think the right course of action in these circumstances is to step aside from the ASX Board to allow the situation to be fully resolved. I look forward to the time when all of the facts and circumstances relevant to this matter are clarified."

Mr Ramy Aziz, will retire in September 2018, after 18 years of service with the Group, including eight years as CFO. ASX Managing Director and CEO, Dominic Stevens, said: "Ramy has made a very significant contribution to ASX over many years and has been an important member of my Executive team. I have valued his support, and the expertise and sound judgement that he has brought to his role as CFO.
